Abstract: 1,234,178. Input devices for signalling systems. INTERNATIONAL BUSINESS MACHINES CORP. 10 Feb., 1970 [28 March, 1969], No. 6226/70. Heading G4H. An input terminal for transmitting data to a control station comprises a plurality of input devices 24, 27, 29, a keyboard T1-Tn for identifying one of several possible transactions, each key being adapted to transmit a corresponding signal to the control station a store 52 for receiving from the control station a signal comprising a guidance code and a control code and means responsive to the guidance code for displaying a guidance instruction to the operator and means responsive to the control code for permitting one of the input devices to transmit data to the control station. When one of the transaction keys is pressed, the corresponding contact T1-Tn marks an associated lead to a transaction code encoder 34. This is passed by gate 35 over leads 36 to the control station. Gate 35 is under the control of send counter 41 and a Transmit instruction Ti from the control station. When the control station has received this code it returns a data received signal which resets latch 43 and disables gate 35 and step counter 41 to 9C. This causes gate 51 to open to read out the zero contents of the guidance code store to the control station over lines 36. No data is sent at this time since the store 52 is reset, and the counter 41 steps to the END position, setting latch 54 and opening gate 56 through gate 57. The next guidance code is then entered into the store 52 from the control station, according to the transaction specified by the operator. The counter then returns to the reset position. The guidance code in the store 52 is applied via decoder 58 is one of the four column leads and via decoder 59 to one of the eight row leads of the array of lamps 23. Each of the 32 lamps has an instruction panel over it to indicate to the operator what he should next do. He may put a job card in a card reader, a badge in a badge reader or key more data in another keyboard. These are shown as data inputs 24, 27 and 29. They are enabled by the second part of the guidance code, two bits of which are decoded at 62 to mark one of leads T1, T2, T3. The sixth bit of the guidance code signal illuminates a lamp 61 showing that further steps are necessary to complete the transaction. The counter 41 steps again to the TC position, sending the transaction code again to the control station. On the next step 9C the guidance code in store 52 is read out again. On the following step DA7A the data is read out from the selected inputs 24, 27, 29. On the END step the next guidance code for the transaction is sent in from the control station to specify the next data input to be activated, and so on until all the required data is sent. Light 61 then goes out.

Abstract: 1,238,552. Imaging methods and apparatus. LITTON BUSINESS SYSTEMS Inc. April 9, 1969 [April 22, 1968], No. 18270/69. Heading G2H. An apparatus for producing a visible image on dielectric material comprises means for producing a high frequency alternating field in the megacycle range, and means for producing a light pattern corresponding to the image on a photo-conductive member, such that when the field is applied to the material breaks in field intensity are produced which correspond to the light pattern and cause a change in appearance by dielectric heating in those areas subject to the higher intensities of field. As shown, a light pattern corresponding to an original is produced on a transparent layer 19 above a transparent conductive layer 21 and an insulating photo-conductive layer 22. A thermographic sheet 15, preferably of polar dielectric comprises one or more sheets of paper 16 each having a heat-sensitive layer 17 which changes visibly when its temperature is sufficiently elevated to expose a coloured surface on the sheet(s) 16. A high frequency voltage source 24 is connected between a conductive plate 23 for a time determined by a timer 25. The areas of layer 17 corresponding to the under illuminated areas 27 of the original negative become heated to produce an image Fig. 2 (not shown). A positive image may be produced by providing illumination according to Fig. 3 (not shown) wherein the light intensity (62) is greater than (G1). In a modification Fig. 8, an insulating photoconductive layer 44 impregnated in or coated in silk, or formed as a coating on glass is in contact with electrodes 42, 43 while exposed to an original 48. A conductivity pattern is formed along the layer 44 corresponding to the original which controls the density of the electrical field applied by source 45. In dark areas the field density is insufficient to heat the thermographic sheet. Positive and negative images may be formed as described with reference to Figs. 13 and 10 (not shown).

Abstract: 1,250,585. Semi-conductor devices. SIEMENS A.G. 19 Dec., 1969 [20 Dec., 1968], No. 61911/69. Heading H1K. A method of manufacturing a semi-conductor component with at least one diffused zone comprises depositing a nickel layer containing a dopant on to a part or parts of a silicon crystal, and diffusing in the dopant to form a zone or zones. A plurality of nickel layers of different thicknesses and containing different dopants may be used to produce zones of differing conductivity or conductivity type. In an embodiment an NPN transistor is formed by depositing a nickel layer containing phosphorus on parts of both faces of a P-doped silicon crystal and subsequently depositing a second nickel layer, containing boron, on the remaining surfaces and the first nickel layer. Diffusing produces a P doped base region 1 with a P<SP>+</SP> region 8 near its surface, and two N<SP>+</SP> regions, an emitter 6 and collector 7. In a second embodiment the first nickel layer is provided with a protective coating and the second nickel layer deposited only on the crystal, diffusion again producing an NPN transistor. In a third embodiment, an N doped crystal has deposited on all surfaces a nickel layer containing boron, which is subsequently diffused in to produce a P<SP>+</SP> region surrounding the N region. Using masking a second nickel layer containing phosphorus is deposited on one part of one surface of the crystal, and a second diffusion takes place producing a small central N region, a surrounding P<SP>+</SP> region and a second N<SP>+</SP> region produced by the second nickel layer. The lower part of the crystal is removed in order to gain access to the central N region, which forms the collector, the second N<SP>+</SP> region forming the emitter.  It is stated that during diffusion a nickelsilicon eutectic, liquid at diffusion temperatures, is formed on the crystal, and that nickel from this eutectic diffuses into the crystal. Specification 1,250,584 is referred to.
